This Science presentation takes the teacher and pupils through a practical lesson exploring the speed of light. Pupils can use everyday items to better understand how light is ‘old’ by the time it reaches Earth by exploring the relative distances between planets! This presentation is aimed at LKS2 but is easily extended, or adapted for assemblies/workshops. Ideal for Space Week or as part of the everyday curriculum if you’re going for an SQEM award. I typically deliver this in Y3’s Light topic as a fun side activity looking at the wider behaviour of Light in our Solar System.
